-Be it known that I, FRANK F. ENO, a citizen of the United States,residing at Boston, in the county of Suffolk, State of Mas sachusetts,have invented an Improvement in `lrVork-Grages for Fastener-InsertingMachines, of which the `following description, in connection with theaccompanying rawings, is a specification, like letters on `the drawingsrepresenting like parts.

This v invention relates to work gages for machines for insertingmetallic or other fasteners in stock, and more articularly to work ga esfor eontrollin the position of heels of oots or shoes wit relation toany convenient form of inserting mechanism.

In securing the 'toplift to a heel pile it is customary to spank thetoplift u on the projecting ends of the heel nails, ut this securinmeans is insufficient to maintain the top ift in position as the shoewears under itsvarious conditions of use. Itis desirable that additionalsecuring means, therefore, be `provided to insure'that the ytoplift willnot become loosened from the heel and be lost Aduring the wearof theshoe. One form of these additional securing means ma consist in aninsertion throng the'iface o the toplift and into the heel pile of oneor more fasteners, of such length that they may project a sufficientdistance into the heel to firmly secure vthe toplift thereto. As theends of these additional fasteners show upon the face of the toplift,where two or more are used they should be so positioned with relation tothel edge of the toplift that they will not mar the a pearance of thefinished shoe, that is, t e series of fasteners should, be placed sym-4metrically upon the to lift.

With these genera considerations in I View, the object of this inventionis to provide-a work age so constructed that securing means additionalto the heel nails, as, for instance, a series of fasteners, vmay beinserted through a toplift and s mmetrically ,withfrelation to its edgewithout the necessity ofthe `operative using his judg- Y' nient inspacing or otherwise positioning them.

My invention will be bestf-understoodby reference tothefollowing'description, when taken in connectionwith the accompanying`drawings showing a specific embodiment:

and 7 are diagrammatic views illustrating the successive positionsa to-lift mayassume during the insertion oft ree additional fasteners.

In the embodiment of` my invention se-` lectedfor illustration h ereinand shown in the accom anying draw1ngs,referri,ng more particular y toFig. 1, A represents the working head of a type of metallic fastenerinserting machine, generally known as the Universal Sluggier, whichmachine 1s fully descr1bed an illustrated in U. S. Patent to L. A.Casgrain, No.786,190, of March 28, 1905. As described in said patent,and moreparticularly in the rior U. S. Patent mentioned therein to L.oddu No. 563,478 for a nailing machine, granted July 7 1896, a driverbar b4 is mounted in suitable guideways behind a fixed face-plate b ofthe machine head, said driver bar having suit-` ably. attached to itadriver b, which enters a driver passage in the nose of the machineduring the-operation of inserting fasteners.

.An awl c is attached to the lower end of an awl bar c', provided at oneside with teeth, which are engaged by teeth on an arm c2 forming part ofa two-armed lever mounted upon a studscrew c, its other arm c* beingprovided with a cam roll 'which enters a roove in the outer face of thecamdisk c, tast u 0,11 the forward end., of the main shaft of. T e 'rearside of the cam disk c,'is provided witli a cam groove, which receives acam roll extendin from the front of the driver bar b, sai cam reciroeating said driver bar positively up and down. The shank of the awlbar `is adapted to slide ver.- tically in ideways in a rocking frame d,having a s eeve-like hub, which embraces a hub surrounding the mainshaft c7', infront of a cam disk a, mounted upon the'main shaft. Therocking'.` frame has suitably at-rv Alios d2, for the awl bar in vitsvertical movement,"

and' at Aits rear side, rocking vframe` has I attached to ita guidewayhaving a movable side d3, which parts are suitably connected to arocking arm d5", connected to a short vrock-shaft d6, having an armv(i7, provided with a cam roll which enters a cam groove in the forwardside of the cam disk als. This' rock-shaft, by engaging the slidingblock, moves the rocking frame to eifectrthe ism, as described, the awl.enters the 'stock through rotation of the cam disk c, while the driveris in-its raised position, and thereafter the cam-'disk a operates,through the rocking connection described, to move the awl bar"laterally,thus feeding the stock and bringing the awl beneath the raised driver.The cam groove controlling the vertical movements ofthe awl` thenoperates to withdraw the awl "from the stock and moves it laterally inthe reverse direction to that for feeding until the awl bar is clear ofthe driver. The cam disk c has been rotated to such a position at thistime that the cam groove controlling the vertical movementsof the driverb", operates to forcethe driver downward quickly and drive a fastener,which, by this time has been placed beneath it. The driver isimmediately withdrawn to its raised position, when the awl againdescends and feeds the stock,as above described. All other featuresofthe machine shown in Fig. 1, are and may be as described in the patentto Casgrain above referred to and therefore need not be referred to indetail herein. As described in said patentv to Casgrain, a gage supportor arm o, is pivoted upon a stud o', mounted vin the frame of, the headA and is acted upon by a spring pin 02, which retains said support inthe elevated or working position shown in the drawing, but permits it tobe depressed when not needed. In the form of the present invention tothe forward end of the support is connected the gage proper B (see Fig.1), the connection being denoted generally bythe letter C. Theconnection C is preferably adjustable and may be of any convenientconstruction, but I prefer to pass a headed screw stud a through a lontudinal slot b, in a portion of a bracket which, in the illustratedembodiment of the invention, supports the engaging portion E, of thework gage, said stud passing through a suitable a erture-iii the supporto. The stud-a, is pre erably provided with a flattened collar a', whichrests within the slot b, and serves as a block on which the work gage Bmay ride when being adjusted. The parts o and D are secured together bymeans of a lock nut a2 lupon the stud a. The lock nut a2, may, ifdesired, be operated by a handle a3. The bracket D is provided with` aseries of pins e, which project into a slot or guidev f,-in the supporto, thus forming a guide for the movement of one part upon the otherduring adjustment and preventing viously be employed, and inorder togive a neat I.appearance to the finished shoe,/tliey are preferablypositioned one at each breast: l

corner of the toplift and one in the center of the rear portion of thelift, which, for convenience, I will term the curve of the fasteners.These stops or stop faces may be formed by constructing said engagingportion, designated generally the letter E, with an irregular workengaging sure face.

more projections or abutments g, preferably oppositely disposed, andwhen so lo-v cated, forming stop portions or faces 7L, the edges formedby the meeting edges of the .faces 71., with the forward faces of theabutments g. forming other stop portions 71X, and the remaining part ofthe engaging portion forming another stopface. n

Referring more particularly to Figs. 5 and 7, the mode of use of thestop faces formed by the abutments g will be readily understood. Thegage is first set, by means of the connection C, so that the face i, ofthe One manner of accomplishing this result is to form upon said portionE, one or engaging portion E, is adjusted relativelyk to the machinehead in such position that when one of the vbreast corners of a topliftis lplaced in engagement with the shoulder formed by one of the stoplfaces it, and the face i, and its edge also engages one of the stopportions h (Figs. 5 or 7), on operat-v ing the machine a fastener willbe inserted the desired distance from the outer edge of the lift. Whenthree fasteners are used,

they are most conveniently inserted in the order shown in Figs, 5 to 7,that is, first at the one breast corner, then at the curve, and,finally, at the remaining breast corner; the lift and slice having been.appropriately turned .bythe operative during this opera-y tion. Duringthis operation the lift engages first one stop portion h, independentlylof the other, then the two stop portions/t,"

simultaneously, and then the other stop portion It', independently ofthe first.

When the gage is to be used with amachine using a type of feed such asan awl-4 feed, for instance, the machine illustrated in Mmm a f Fig.` 1,means should be providedA for allowingthe gage a transverse movementwith vthe feed of the stock, which movement,'bow

ever, is not neceary where a form of feed is used that moves the stockafter a fastener has been inserted. In order to provide for thistransverse movement of the ga e, when it is necessary, I have shown thes ank of the engagin portion E as pivotall mount ed at y, on the bracketand mova le yieldingly in the direction of feed, for example, against aleaf spring k. In order to maintain the symmetry of the fasteners thusinserted, it 1s obvious that' those at the breast corners should besimilarly spaced from the breast edge of the tophft, as well as from theouter edge of the lift Vand the fastener at the curve of the heel shouldbe centrally disposed with relation to the two breast corner fasteners,If the engagin portion E, ofthe gage B, is located centra lytransversely lwith relation to the awl of the inserting mechanism, orifl an awl is not used, with relation to the point at which the fastenerleaves the machine, then the stop faces formed, as described, by theabutments, are

equi-distant'laterally fromfthe awl or from the point where the fastenerleaves the machine. When in such location these stops will control theposition of the heel for receivingjasteners at the breast corners andwill insure that the fastener at one breast corner is inserted the samedistance from the breast edge as the fastener `atthe other breastcorner. By reference to Figs. 5 and 7, it is seen that the describedstop portions or faces form means to maintain the breast corners of theheel in such position with relation to the inserting mechanism that each:fastener will be inserted in the same location with relation to theangle of its breast corner.

Frequently, when the work gage is placed upon a machine, its su port o,is out of alinement and, therefore, w en the engaging portion E, isproperly adjusted longitudinally relatively to the inserting mechanism,the awl, or the point where the fasteners leave the machine, as the casemay be, will not be centrally located between the stop faces h, In thiscase it is obvious that as the heel is turned to receive the fastenersat its breast corners, one of said fasteners would be nearer thel breastedgethan the other, according to the amount that the gage is off centertransversely. In order to remed this defect I have provided transverse ajustin means, generally designated by the'letter i, which may consist`ofv a set screw l, threaded through a lug m, on the bracket D, and heldin any position of adjustment by means of a lock nut n, the gage, in theillustrated em bodiment of the invention, being maintained against theend of said set screw by means of the spring la. With this construction,when it is found that the engaging portion E, of the work gage is notcentrally isposed with relation to the inserting mechanism, as it shouldbe, the set screw adjust the gage transversely until such centrallocation 1s obtained and is then locked in position. I have, throughthis adJustment, provided means for insuring a symmetrical location ofthe fasteners at the breast corners of the heel, without regard towhether the sup ort o is inproper alinemenhwith the mac ine ame.`

Frequently, the location of the heel nails is such that if theadditional fastener at the curve of the heel were 'placed the samedistance from the outer edge of the toplift as the fasteners at thebreast corners, the awl in making its hole for the. fastener, or thefastener itself as it is driven, as the case may be, will strike one ofthe heelnails. As a result, either the awl will be broken or thefastener will be bent and will not enter the heel. The locationof theheel nails within the toplift can enerally be' determined bydiscoloration of t e leather, or by other indicating marks well-known tothe shoe o'.\erative2 so that when the toplift is placed in position toreceive its fastener at the curve,

yhe can tell by inspection whether or not the additional fastener willbe driven upon a heel nail. If it hap ens that such is going to be thecase, the a ditional fastener atthe t curve should be inserted inside ofthe line of heel nails butstill centrally with relation to the breastnails, so that the s mmetr of the three fasteners will not be disturbs Iprefer to provide for allowin this to be is turned so as to one bymovably mounting t e en aging portion E, upon, its supportin brac ret D,preferably yieldin ly, as genera ly indicated by the character A iReferring more particularly to Figs. 2 to 4, the shank of the en agingportion E, is slidably mounted in a rame p, which forms a suitableguideway and is retained within the frame by means of cross bars g,extend- ,ing across its top. A coil spring 1', is connected at one endto avpin on the engaging lportion E, and at its other end to a pin uponone of the cross bars g, in such position that the portion E, isnormally maintained in its forward position. This movement may belimited by means of a shoulder s on the portion E, arranged to abutagainst one of the cross pieces q. Any convenient means may be emplo edto limit the rearward movement of t e engaging portion E. As shown, theforward end of its shank is preferably in a different horizontal planefrom the rearend theref,-see Fig. 3,-and when so constructed theshoulder t, thus formed limits the rearward movement by abutting againstone of the cross pieces g. With this construction it is readilyseen-that ifthe position of the heel nails is such that they conflirtwith the insertion of the additional fastener at the curve of the heelthe operative may, by pressure ugon the shoe, move the shanklof theportion longitudinally in its uide against the force of the spring 1',unt the heel has reached a position where the additional fastenerwill'clear the heel nails, when it may be inserted. It is obvious thatthis longitudinal movement of the gage merely brings the fastener at thecurve of the heelnearer to the fasteners at the Ybreast corners and doesnot alter its transverse relation to'said fasteners, therefore reservingtheir symmetrical relation as is esired.

In practice, when no slugs are to be inserted' in the heel the threeladditional fasteners are preferably inserted quite near the edge of thetoplift, but if the heel is to be slugged the relation of the additionalfasteners vto the edge of the toplift should be altered accordin tothelocation and amount of slugging to e done. For instance, if the heel isto be quarteror half slugged it is only necessar to Place the fastenerat the curve of the eel artherin from the edge, and this is done bymoving the engaging portion E, longitudinally, when that fastener is tobe inserted, as just described. If, however, the heel is to-be fullslugged, the fasteners at the breast corners should also be moved inwardfrom the edge of the'lift, so as not to conflict with the line ofslugging and, therefore, in shoes where this form 'of sluggin is used,the portion E, is moved longitu inally against the spring r, for allthree fasteners. Obviously, however, where vthe additional fasteners areto be inserted into a number of shoes, successively, that are to be fullslugged later, the work maybe done morequickly by adjusting the gage B,on its support o, to such position that all fasteners will be driven theincreased distance inward without the necessity of using the yieldingmounting G. If three-quarter slugging is used only one of thebreastcorner fasteners would conflict with the slugging but, in order topreserve the symmetrical relation of the three fasteners, all three',the breast ed e always remains theV same.

0f course, t is latter relation could -be changed, if desired, byspacing the stop faces h, farther apart or nearer'together,

-justment t which could bc readily done by inserting another part orotherwise modifying the construction of the work engagin Surface.

In -the operation of the mac ine after adrough'the connection and thedevices F, as hereinbefore described, one breastcorner of the heel isplaced in contact with one of the abutments g, in such position that aplurality of the stop portions or faces are engaged see Fi 5) so'as tocontrol the position of t e stoc a ainst movementin two directions, anda astener is inserted usuall without ressing the engaging portionbackwar longitudinally. The shoe is then turneduntil the curve of theheel rests either against the sto face i, or a ainst the stop portionsIt', accor lin to the re ative size or contour of the heel an engagingportion E, and a fastener is driven centrall of the curve' of the tolift, the portion. being pressed backwar as shown in Fig. 6, or not, asis found necessary. When the to lift is so small that its curve engageson y the stop t and not the stops h', it is convenient to form in thestop face i, a recess or depression as i', which may be V-shaped, asshown, or of any other configuration that will ald in centering the heelwith relation to the inserting mechanism. The shoe is then turned tilthe other breast corner rests agains the other abutment g, and the stopfaces formed thereby see Fig. 7) and a third fastener'is inserted w ilethe heel is in this manner maintained in correct position with relationto the inserting mechanism.

Obviously, the construction as herein illustrated,may be varied andchanged in numerous articulars without departing from the spirit andscope of my invention and nothing herein contained is to be construed aslimiting my invention in sco e to the particular embodiment selected ferillustration and explanation. Such alteration and modiication will beapparent to those skilled in the art.
